The Food Bureau issued a survey report on the quality of wheat harvest in the summer of 2011 in the country

In order to keep abreast of the quality of wheat harvest in the summer of 2011, the State Grain Administration organized inspections of wheat quality in nine provinces of Hebei, Shanxi, Jiangsu, Anhui, Henan, Shandong, Hubei, Sichuan, and Shaanxi. The sample distribution was weighted according to the yield, and 1954 samples of wheat were collected in 9 provinces. The samples covered 421 counties in 92 cities.

All test results showed that the bulk density varied from 674 to 832 g/L with an average of 780 g/L, and the first to fifth equal percentages were 37%, 35%, 21%, 5%, and 2%, respectively. Etc.) accounted for 93% of the above. 1000-grain heavy variation ranged from 26.7g to 56.1g with an average value of 42.2g, a decrease of 0.7g from the previous year.
